技术领域technical field

本申请涉及无线通信领域，尤其涉及一种通信方法及相关设备。The present application relates to the field of wireless communication, and in particular, to a communication method and related equipment.

背景技术Background technique

在通信***中，终端设备和网络设备建立通信之前，终端设备需要解调来自网络设备的同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCHblock或SSB)获取用于初始接入的重要信息，以接入该网络设备，其中，SSB也可以简称为同步信号块或初始接入信号。In a communication system, before a terminal device and a network device establish communication, the terminal device needs to demodulate the synchronization signal/physical broadcast channel block (SS/PBCHblock or SSB) from the network device to obtain it for initial connection In order to access the network device, SSB can also be referred to as a synchronization signal block or an initial access signal for short.

目前，针对同一个SSB，网络设备可以在具有关联关系的一个或多个下行发送波束方向上发送该SSB，以提升终端设备的接入成功率。其中，终端设备通过指示候选SSB位置的参数确定不同的候选SSB位置，并通过候选SSB位置之间的关联参数确定不同候选SSB位置之间的关联关系。其中，该关联关系一般通过3-比特(bits)的解调参考信号(demodulation reference signal，DMRS)序列进行指示，即该DMRS可以通过3-bits指示8个或8个以下的不同候选SSB位置之间的关联关系。Currently, for the same SSB, the network device may send the SSB in one or more downlink transmit beam directions with an associated relationship, so as to improve the access success rate of the terminal device. Wherein, the terminal device determines different candidate SSB positions through a parameter indicating the candidate SSB positions, and determines the association relationship between the different candidate SSB positions through the association parameter between the candidate SSB positions. Wherein, the association relationship is generally indicated by a 3-bit (bits) demodulation reference signal (demodulation reference signal, DMRS) sequence, that is, the DMRS can indicate one of 8 or less different candidate SSB positions by 3-bits relationship between.

然而，当网络设备用于发送SSB的候选SSB位置的数量较多，例如大于8个时，由于该关联参数无法指示数量较多的不同候选SSB位置之间的关联关系，容易导致终端设备解调SSB失败，增大终端设备接入时延。However, when the number of candidate SSB positions used by the network device for sending SSB is large, for example, more than 8, since the correlation parameter cannot indicate the correlation between the large number of different candidate SSB positions, it is easy to cause the terminal equipment to demodulate SSB fails, increasing the access delay of terminal equipment.

"At least one" means one or more, and "plurality" means two or more. "And/or", which describes the association relationship of the associated objects, means that there can be three kinds of relationships, for example, A and/or B, which can mean: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A, B can be singular or plural. The character "/" generally indicates that the associated objects are an "or" relationship. "At least one item(s) below" or similar expressions thereof refer to any combination of these items, including any combination of single item(s) or plural items(s). For example "at least one of A, B and C" includes A, B, C, AB, AC, BC or ABC.

本申请可以应用于如图1所示非授权频段(unlicensed band)的通信***中，包括网络设备和多个终端设备(UE)。在该通信***中，UE1-UE5都可以和网络设备进行通信，其链路环境包括了上行、下行以及侧行链路(Side-link)，链路中传输的信息包括了实际传输的数据信息，以及用于指示或调度实际数据的控制信息。同时，UE3，UE4和UE5也可以组成一个通信***，其链路传输环境和前述一致，具体的信息交互可以依托于网络的配置方式。The present application can be applied to an unlicensed band (unlicensed band) communication system as shown in FIG. 1 , including network equipment and multiple terminal equipments (UEs). In this communication system, UE1-UE5 can all communicate with network equipment, the link environment includes uplink, downlink and side-link, and the information transmitted in the link includes actually transmitted data information , and control information to indicate or schedule actual data. At the same time, UE3, UE4 and UE5 can also form a communication system, and the link transmission environment thereof is the same as the above, and the specific information exchange can depend on the configuration of the network.

通过将通信***部署到共享(非授权)频段上，不但可以提升通信***的吞吐量，还可以解决频谱资源紧缺的问题。在第五代移动通信技术背景框架下，将部署在共享频段的技术统一叫做新无线非授权(new radio unlicensed，NRU)。在共享频段上，除了当前的新空口(new radio，NR)***之外，还包括其它诸如雷达(radar)、无线保真(wireless fidelity，WIFI)、蓝牙及其它异运营商的接入***，因此，法规规定工作在共享频段上的***需要支持如下所有或者部分关键技术，即先听后说机制(listen before talk，LBT)、发送功率控制(transmit power control，TPC)和动态频谱选择(dynamic frequency selection，DFS)。其中，LBT机制是指各种接入设备在使用信道之前都要先去获取目标信道所在频段上的干扰情况，只有当目标频段信道上的干扰水平小于等于预设门限值，才能使用该信道。TPC机制是指为了不影响其它接入设备的正常通信，工作在共享授权上的发送设备不能无限制的提升自身的发射功率。DFS机制是指工作在共享授权上***需要及时的避开高优先级***所在的频段，动态切换到干扰较低的频段上工作。By deploying the communication system on the shared (unlicensed) frequency band, not only the throughput of the communication system can be improved, but also the problem of shortage of spectrum resources can be solved. Under the background of the fifth-generation mobile communication technology, the technologies deployed in the shared frequency band are collectively called new radio unlicensed (new radio unlicensed, NRU). In the shared frequency band, in addition to the current new radio (NR) system, it also includes other access systems such as radar (radar), wireless fidelity (WIFI), Bluetooth and other different operators. Therefore, regulations stipulate that systems operating in shared frequency bands need to support all or some of the following key technologies, namely, listen before talk (LBT), transmit power control (TPC) and dynamic spectrum selection (dynamic spectrum selection). frequency selection, DFS). Among them, the LBT mechanism means that various access devices must first obtain the interference situation on the frequency band where the target channel is located before using the channel. Only when the interference level on the target frequency band channel is less than or equal to the preset threshold value, the channel can be used. . The TPC mechanism means that in order not to affect the normal communication of other access devices, a sending device working on a shared authorization cannot increase its own transmit power without limitation. The DFS mechanism means that the system working on the shared license needs to avoid the frequency band where the high-priority system is located in time, and dynamically switch to the frequency band with lower interference to work.

示例性的，以用户设备(UE)为终端设备，基站(gNB)为网络设备为例，用户设备和基站建立通信之前将会进入初始接入的过程，UE首先通过解调同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block或SSB或SSB index或SS/PBCH block index)获取用于初始接入的重要信息。其中，SSB主要由主同步信号(primary synchronization signal，PSS)，辅同步信号(secondary synchronization signal，SSS)和物理广播信道(physical broadcast channel，PBCH)组成，时频域上为跨越4个正交频分复用符号(orthogonal frequency division multiplexing，OFDM)和频域上占20个资源块(resource blocks，RBs)的二维区域。Exemplarily, taking the user equipment (UE) as the terminal device and the base station (gNB) as the network device as an example, the initial access process will be entered before the user equipment and the base station establish communication. The UE first demodulates the synchronization signal/physical broadcast The channel block (synchronization signal/physical broadcast channel block, SS/PBCH block or SSB or SSB index or SS/PBCH block index) acquires important information for initial access. Among them, SSB is mainly composed of primary synchronization signal (PSS), secondary synchronization signal (SSS) and physical broadcast channel (PBCH). The two-dimensional area occupies 20 resource blocks (RBs) in the frequency domain.

具体的，通信***允许的最大发送SSB数量和当前***所在的频段有关。对于支持频分复用模式(frequency-division duplex，FDD)的***来说，当UE和gNB在小于等于3兆赫兹(GHz)的频段工作时，gNB发送的最大SSB数量为4；对于时分复用模式(time-division duplex，TDD)***来说，当UE和gNB在小于等于2.3GHz的频段工作时，gNB发送的最大SSB数量为4。此时，UE通过解调SSB中映射到PBCH中3-比特(bits)的解调参考信号(demodulation reference signal，DMRS)序列(该DMRS序列共占3-bits)获取候选SSB位置。对于FDD***，当UE和gNB在大于3GHz及小于6GHz之间的频段上工作时，gNB发送的最大SSB数量为8；对于TDD***，当UE和gNB在大于2.3GHz以及小于6GHz之间的频段上工作时，gNB发送的最大SSB数量为8，UE通过解调SSB中3-bits的DMRS序列获取候选SSB位置。Specifically, the maximum number of transmitted SSBs allowed by the communication system is related to the frequency band in which the current system is located. For systems that support frequency-division duplex (FDD), when the UE and gNB operate in a frequency band less than or equal to 3 megahertz (GHz), the maximum number of SSBs sent by the gNB is 4; for time-division duplex In a mode (time-division duplex, TDD) system, when the UE and the gNB work in a frequency band less than or equal to 2.3 GHz, the maximum number of SSBs sent by the gNB is 4. At this time, the UE obtains the candidate SSB position by demodulating the demodulation reference signal (DMRS) sequence (the DMRS sequence occupies 3-bits) mapped to the 3-bit (bits) in the PBCH in the SSB. For the FDD system, when the UE and the gNB operate in the frequency band greater than 3GHz and less than 6GHz, the maximum number of SSBs sent by the gNB is 8; for the TDD system, when the UE and the gNB operate in the frequency band greater than 2.3GHz and less than 6GHz When working, the maximum number of SSBs sent by the gNB is 8, and the UE obtains the candidate SSB positions by demodulating the 3-bit DMRS sequence in the SSB.

当通信***工作的频段大于6GHz时，gNB可发送的SSB数量最多为64个，它通过PBCHpayload(PBCH负载)中的3-bit(以

表示)和表示3-bits的DMRS序列，共计6-bits表示。针对所发送的64个SSB，***引入了组的概念，即参数“ssb-PositionsInBurst”中包含了“groupPresence”和“inOneGroup”。参数“groupPresence”表示一组连续的SSBs，参数“inOneGroup”表示在组“groupPresence”内实际发送的SSB位置，不同组中的SSN图样(SSBpattern)相同。 When the frequency band of the communication system is greater than 6GHz, the maximum number of SSBs that can be sent by the gNB is 64.

represents) and represents the DMRS sequence of 3-bits, representing a total of 6-bits. For the 64 SSBs sent, the system introduces the concept of a group, that is, the parameter "ssb-PositionsInBurst" includes "groupPresence" and "inOneGroup". The parameter "groupPresence" indicates a group of consecutive SSBs, and the parameter "inOneGroup" indicates the actual SSB position sent in the group "groupPresence", and the SSN patterns (SSBpatterns) in different groups are the same.

比如，当UE解调出的

时，其中，

对应“000000”中的前三个比特，“DMRS序列”对应“000000”中的后三个比特。“000000”表示UE解调出的候选SSB位置

为#0，对应的组位置为#0；当UE解调出的

时，表示UE解调出的候选SSB位置为#7，对应的组位置为#0；当UE解调出的

时，表示UE解调出的候选SSB位置为#15，对应的组位置为#1。 For example, when the UE demodulates the

, of which,

Corresponding to the first three bits in "000000", "DMRS sequence" corresponds to the last three bits in "000000". "000000" indicates the candidate SSB position demodulated by the UE

is #0, and the corresponding group position is #0; when the UE demodulates the

, it indicates that the candidate SSB position demodulated by the UE is #7, and the corresponding group position is #0;

, it indicates that the candidate SSB position demodulated by the UE is #15, and the corresponding group position is #1.

再比如，假设“groupPresence＝10101011，inOneGroup＝10101011”，其SSB的发送示例图如附图2所示。从图2中，可以发现，对于网络设备来说，参数“groupPresence”中取值为“1”的位置指示需要发送的包含SSB的组；参数“inOneGroup”取值为“1”的位置指示了每个组中需要发送的SSB位置，每个组中发送的SSB pattern都一样，即都为“10101011”。相应的，对于终端设备来说，参数“groupPresence”中取值为“1”的位置指示实际需要接收的包含SSB的组；参数“inOneGroup”取值为“1”的位置指示了每个组中实际需要接收的SSB位置，每个组中接收的SSB pattern都一样，即都为“10101011”。For another example, assuming "groupPresence=10101011, inOneGroup=10101011", an example diagram of SSB sending is shown in Fig. 2 . From Figure 2, it can be found that, for the network device, the position of the parameter "groupPresence" with the value of "1" indicates the group containing the SSB to be sent; the position of the parameter "inOneGroup" with the value of "1" indicates the The position of the SSB to be sent in each group, and the SSB pattern sent in each group is the same, that is, "10101011". Correspondingly, for a terminal device, the position of the parameter "groupPresence" with the value of "1" indicates the group containing the SSB that actually needs to be received; the position of the parameter "inOneGroup" with the value of "1" indicates the The actual SSB location that needs to be received, the received SSB pattern in each group is the same, that is, "10101011".

其中，参数“ssb-PositionsInBurst”被包含在***信息块1(system information block1，SIB1)中。对gNB来说，其在通过物理下行控制信道(physical downlink control channel，PDCCH)/物理下行共享信道(physical downlink shared channel，PDSCH)给UE传输数据时，所分配的时频域资源将会避开发送SSB所占用的时频域资源。对UE来说，其通过解调参数“ssb-PositionsInBurst”之后，其认为发送SSB的时频域资源上不存在所调度的PDCCH/PDSCH资源，也即是我们常理解的速率匹配(rate matching，RM)。Among them, the parameter "ssb-PositionsInBurst" is included in the system information block 1 (system information block1, SIB1). For the gNB, when it transmits data to the UE through the physical downlink control channel (PDCCH)/physical downlink shared channel (PDSCH), the allocated time-frequency domain resources will be avoided. Time-frequency domain resources occupied by the sending SSB. For the UE, after passing the demodulation parameter "ssb-PositionsInBurst", it believes that there is no scheduled PDCCH/PDSCH resource on the time-frequency domain resources for sending SSB, which is the rate matching that we often understand. RM).

目前，当终端设备和网络设备在共享频段上通信时，考虑到LBT机制的存在，Rel-16的NRU***分别定义了突发集信号/发现参考信号(discovery reference signal，DRS)窗口和候选SSB位置(candidate SSB index/position，

)的概念。其中，DRS窗口的持续时间可以为{0.5ms，1ms，2ms，3ms，4ms，5ms}。对于UE来说，默认一组SSBs(SS burst set)在DRS窗口内发送。Rel-16的NRU***主要工作的频段在6GHz以下，其可支持的最大发送SSB个数为8个。因此，在最长为5ms的DRS窗口内，当子载波间隔(sub-carrier sacing,SCS)为15千赫兹(KHz)时，

它通过PBCH payload(PBCH负载)中的

和3-bits的DMRS序列，共计4-bits指示；当子载波间隔为30KHz时，

它通过PBCH payload(PBCH负载)中的

和3-bits的DMRS序列，共计5-bits指示。也即比如，当子载波间隔为30KHz且DRS窗口为5ms时，共有20个候选位置用于发送实际的SSB位置(l)。这里需要说明的是，SIB1中的参数“ssb-PositionsInBurst”所指示的为l，表示的是实际发送的SSB位置，而非

At present, when the terminal device and the network device communicate on the shared frequency band, considering the existence of the LBT mechanism, the NRU system of Rel-16 defines the burst set signal/discovery reference signal (DRS) window and candidate SSB respectively. position(candidate SSB index/position,

)the concept of. The duration of the DRS window may be {0.5ms, 1ms, 2ms, 3ms, 4ms, 5ms}. For the UE, by default a set of SSBs (SS burst set) are sent within the DRS window. The main working frequency band of the NRU system of Rel-16 is below 6GHz, and the maximum number of SSBs it can support is 8. Therefore, in a DRS window of up to 5ms, when the sub-carrier spacing (SCS) is 15 kilohertz (KHz),

It passes the PBCH payload (PBCH payload) in

and 3-bits DMRS sequence, a total of 4-bits indication; when the subcarrier spacing is 30KHz,

It passes the PBCH payload (PBCH payload) in

and 3-bits DMRS sequence, a total of 5-bits indication. That is, for example, when the subcarrier spacing is 30KHz and the DRS window is 5ms, there are 20 candidate positions in total for transmitting the actual SSB position (1). It should be noted here that the parameter "ssb-PositionsInBurst" in SIB1 indicates 1, which indicates the actual sent SSB position, not the

即在共享频段上通信时，针对同一个SSB，网络设备可以在具有关联关系的一个或多个下行发送波束方向上发送该SSB，以提升终端设备的接入成功率。其中，终端设备通过指示SSB位置的参数确定不同的SSB位置，并通过SSB位置之间的关联参数确定不同SSB位置之间的关联关系。具体地，考虑到实际发送SSB位置(l)可以在多个候选位置

上发送，***引入了准共址(quasi co-location，QCL)的概念，通过公式

或

表示，

表示SSB中映射到PBCH的DMRS的序列，

为Q值，占用2-bits，取值{1，2，4，8}。UE通过解调主信息块(master information block，MIB)获取

当候选SSB位置

上的实际SSB位置(l)满足公式

或

时，gNB会在满足公式的候选位置

上发送相同的SSB位置(l)。对UE来说，其对应同一个SSB位置，UE可使用同一个下行接收波束接收满足公式的SSB位置(l)。 That is, when communicating on the shared frequency band, for the same SSB, the network device can send the SSB in the direction of one or more downlink transmit beams with an associated relationship, so as to improve the access success rate of the terminal device. Wherein, the terminal device determines different SSB positions through a parameter indicating the SSB position, and determines the association relationship between different SSB positions through the association parameter between the SSB positions. Specifically, considering that the actual transmission SSB position (1) can be in multiple candidate positions

The system introduces the concept of quasi co-location (QCL), through the formula

or

When , the gNB will be in the candidate position that satisfies the formula

send the same SSB position (l) on the For the UE, it corresponds to the same SSB position, and the UE can use the same downlink receive beam to receive the SSB position (1) that satisfies the formula.

需要说明的是，本实施例及后续实施例中，满足公式“A mod B”，用于表示“A”可以被“B”整除，或者表示“A”除以“B”的余数为0。例如，当A取值为16时，B取值为1/2/4/8/16时，确定A和B满足公式“A mod B”，显然，当B取值为3/5/6/7/9/10/11时，确定A和B不满足公式“A mod B”。It should be noted that, in this embodiment and subsequent embodiments, the formula "A mod B" is satisfied, which is used to indicate that "A" can be divisible by "B", or that the remainder of "A" divided by "B" is 0. For example, when the value of A is 16 and the value of B is 1/2/4/8/16, it is determined that A and B satisfy the formula "A mod B". Obviously, when the value of B is 3/5/6/ On 7/9/10/11, it is determined that A and B do not satisfy the formula "A mod B".

为便于说明

和(l)的关系，假设

5ms内具有QCL关系(QCLed)的候选SSB示意图如附图3所示。在该图示中，DRS窗口的长度为5ms，第一行的#0～#19表示候选SSB位置

当Q＝4，第二行中，图案相同的候选SSB位置为QCLed的候选SSB位置。例如，图案相同的候选SSB位置#0、候选SSB位置#4、候选SSB位置#8、候选SSB位置#12、候选SSB位置#16为QCLed的候选SSB位置；又如，图案相同的候选SSB位置#3、候选SSB位置#7、候选SSB位置#11、候选SSB位置#15、候选SSB位置#19为QCLed的候选SSB位置。对UE来说，可使用同一个下行接收波束在接收来自不同候选位置上图案相同的SSB。 For ease of explanation

and (l), assuming

A schematic diagram of candidate SSBs with a QCL relationship (QCLed) within 5 ms is shown in FIG. 3 . In this illustration, the length of the DRS window is 5ms, and #0 to #19 in the first row represent candidate SSB positions

When Q=4, in the second row, the candidate SSB positions with the same pattern are the candidate SSB positions of QCLed. For example, candidate SSB position #0, candidate SSB position #4, candidate SSB position #8, candidate SSB position #12, and candidate SSB position #16 with the same pattern are QCLed candidate SSB positions; another example, candidate SSB positions with the same pattern #3, candidate SSB position #7, candidate SSB position #11, candidate SSB position #15, and candidate SSB position #19 are the candidate SSB positions of QCLed. For the UE, the same downlink receive beam can be used to receive SSBs with the same pattern from different candidate positions.

针对图2的示例，在引入LBT时，其示例图附图4所示。在图4中，当LBT在第一个组内的候选SSB位置#21处LBT成功，即SSB位置#1～#5因为LBT失败无法发送，如果使用Rel-16NRU***中的循环方式，组#1中参数“inOneGroup”变成“11101010”，而其它组中参数“inOneGroup”也可能即将发生改变。即，当网络设备发送的SSB数量较多，需要以SSB组的形式发送SSB时，例如，当发送的SSB的数量为64时，每个组内参数“inOneGroup”将会发生改变，以至于UE无法进行合适的速率匹配。此外，由于该关联参数仅仅指示不同SSB位置之间的关联关系，容易导致终端设备解调SSB失败，增大终端设备接入时延，影响通信效率。For the example of FIG. 2 , when LBT is introduced, its example diagram is shown in FIG. 4 . In Figure 4, when LBT is successful at candidate SSB position #21 in the first group, that is, SSB positions #1 to #5 cannot be sent due to LBT failure, if the round-robin method in the Rel-16NRU system is used, group # The parameter "inOneGroup" in 1 becomes "11101010", and the parameter "inOneGroup" in other groups may also be about to change. That is, when the network device sends a large number of SSBs and needs to send SSBs in the form of SSB groups, for example, when the number of SSBs sent is 64, the parameter "inOneGroup" in each group will change, so that the UE Unable to do proper rate matching. In addition, since the association parameter only indicates the association relationship between different SSB positions, it is easy to cause the terminal device to fail to demodulate the SSB, increase the access delay of the terminal device, and affect the communication efficiency.

为了解决上述问题，本申请实施例提供了一种通信方法及相关设备，用于提升终端设备解调SSB的成功率，在初始接入过程中，缩短了终端设备初始接入的接入时延，提高了初始接入的可靠性，从而提升通信效率。In order to solve the above problems, the embodiments of the present application provide a communication method and related equipment, which are used to improve the success rate of terminal equipment to demodulate SSB, and shorten the access delay of the terminal equipment's initial access during the initial access process. , which improves the reliability of initial access and improves communication efficiency.

The SSB is sent on the resource corresponding to the SSB. Correspondingly, for the terminal device, the SSB may be received based on the candidate SSB. In different embodiments, candidate SSBs may also be referred to as "candidate SSB positions", or "candidate SSB indices", or "candidate positions"; candidate SSB groups may also be referred to as "candidate SSB group positions", or "candidate SSB positions" group index", or "candidate group position". Hereinafter, the "candidate SSB group position" and the "candidate SSB position" will be described as examples.

具体地，网络设备在步骤S104发送SSB之前，通过步骤S101中首先确定需要发送的SSB所在的多个候选SSB组位置，其中，多个候选SSB组位置中至少两个候选SSB组位置具有关联关系。该关联关系具体可以包括准共址(quasi co-location，QCL)关系。Specifically, before sending the SSB in step S104, the network device first determines, in step S101, multiple candidate SSB group positions where the SSB to be sent is located, wherein at least two candidate SSB group positions in the multiple candidate SSB group positions have an association relationship . The association relationship may specifically include a quasi co-location (QCL) relationship.

在步骤S101中，网络设备可以根据当前通信的频段、当前通信的信道占用比(channel occupancy ratio，CR)、信道忙碌比(channel busy ratio，CBR)等网络参数在步骤S101中确定多个候选SSB组位置；网络设备也可以根据预制的配置信息、核心网设备或者其它网络设备的指示信息在步骤S101中确定多个候选SSB组位置，或者是通过其它的方式确定，此处不做限定。In step S101, the network device may determine multiple candidate SSBs in step S101 according to network parameters such as the frequency band of the current communication, the channel occupancy ratio (CR) of the current communication, and the channel busy ratio (CBR), etc. Group location; the network device may also determine multiple candidate SSB group locations in step S101 according to prefabricated configuration information, core network device or other network device indication information, or determine by other means, which is not limited here.

Accordingly, the terminal can receive the SSB at the above-mentioned position.

具体地，该第一指示信息具体可以通过物理广播信道PBCH负载和/或解调参考信号DMRS序列对应的比特来联合表示，即该第一指示信息可以通过物理广播信道PBCH负载中的比特和/或表示解调参考信号DMRS序列的比特实现。其中，该第一指示信息对应的总比特数可以为n个，其中，该n为4、5或7，或者是其它的取值，例如3、6、8等，且n的不同的取值可以对应于第一指示信息所指示多个候选SSB组位置的候选SSB组对应的不同数量。示例性地，当n取值为3时，第一指示信息可以通过物理广播信道PBCH负载中的任意3-bits表示，或者，第一指示信息也可以通过DMRS序列对应的3-bits表示，或者是通过物理广播信道PBCH负载和DMRS序列联合表示。Specifically, the first indication information may be expressed jointly by the physical broadcast channel PBCH load and/or the bits corresponding to the DMRS sequence of the demodulation reference signal, that is, the first indication information may be expressed by the bits in the physical broadcast channel PBCH load and/or the bits corresponding to the DMRS sequence of the demodulation reference signal. Or represents the bit realization of the demodulation reference signal DMRS sequence. The total number of bits corresponding to the first indication information may be n, where n is 4, 5, or 7, or other values, such as 3, 6, 8, etc., and different values of n The number of candidate SSB groups corresponding to the multiple candidate SSB group positions indicated by the first indication information may be different. Exemplarily, when n is 3, the first indication information can be represented by any 3-bits in the PBCH load of the physical broadcast channel, or the first indication information can also be represented by the 3-bits corresponding to the DMRS sequence, or It is expressed jointly by the physical broadcast channel PBCH load and the DMRS sequence.

相应的，终端设备在步骤S102中接收得到第一指示信息之后，可以根据第一指示信息所包含的PBCH负载和/或解调参考信号DMRS的不同实现，确定多个候选同步信号块SSB组位置。下面将通过具体的示例，对终端设备根据第一指示信息的不同实现确定多个候选同步信号块SSB组位置的过程进行描述，在如下示例中，以Z表示多个候选同步信号块SSB组位置。其中，作为一种可能的实现方式，对于候选组位置Z的表示方式，可通过如下几种方式中的至少一种进行表示：Correspondingly, after the terminal device receives the first indication information in step S102, it can determine the SSB group positions of multiple candidate synchronization signal blocks according to the PBCH load and/or the different implementations of the demodulation reference signal DMRS contained in the first indication information. .

三、终端设备也可通过指示候选SSB位置的配置参数中隐含获取得到第一指示信息，即第一指示信息可以通过指示候选SSB位置的配置参数实现。其中，在一个DRS窗口(或者一个半帧或者一个SS burst set周期)内，候选SSB位置可通过“

+指示DMRS序列中的3-bits”，共计7-bits表示。 3. The terminal device can also obtain the first indication information implicitly through the configuration parameter indicating the position of the candidate SSB, that is, the first indication information can be realized by the configuration parameter indicating the position of the candidate SSB. Among them, within a DRS window (or a half frame or a SS burst set period), the candidate SSB position can be passed through "

+ Indicates 3-bits in the DMRS sequence", a total of 7-bits are represented.

此时，终端设备可以通过候选SSB位置

Correspondingly, the terminal device receives the second indication information from the network device in step S103.

在一种可能的实现方式中，网络设备在步骤S101确定得到的多个候选SSB组位置中，至少两个候选SSB组位置存在的关联关系，可以存在多种实现方式，此时，第二指示信息可以通过不同的参数，以确定该关联关系的多种实现方式。例如，当至少两个候选SSB组位置包括第一候选SSB组位置和第二候选SSB组位置时，该第二指示信息可以用于指示该第一候选SSB组位置和该第二候选SSB组位置之间具有该关联关系；和/或，当至少两个候选SSB组位置包括第三候选SSB组位置和第四候选SSB组位置，该第二指示信息可以用于指示该第三候选SSB组位置中的至少一个候选SSB位置和该第二候选SSB组位置中的至少一个候选SSB位置之间具有该关联关系。In a possible implementation manner, among the multiple candidate SSB group positions determined by the network device in step S101, the association relationship between at least two candidate SSB group positions may exist in multiple implementation manners. In this case, the second indication Information can be passed through different parameters to determine multiple implementations of the association. For example, when the at least two candidate SSB group positions include a first candidate SSB group position and a second candidate SSB group position, the second indication information may be used to indicate the first candidate SSB group position and the second candidate SSB group position and/or, when at least two candidate SSB group positions include a third candidate SSB group position and a fourth candidate SSB group position, the second indication information may be used to indicate the third candidate SSB group position There is the association relationship between at least one candidate SSB position in the second candidate SSB group position and at least one candidate SSB position in the second candidate SSB group position.

具体地，用于确定多个候选SSB组位置中，至少两个候选SSB组位置所具有的关联关系的第二指示信息可以存在多种实现方式。该第二指示信息具体可以指示至少两个候选SSB组位置中的不同SSB组之间关联关系，和/或，该第二指示信息具体可以指示至少两个候选SSB组位置中的不同SSB组所包含的至少一个候选SSB位置之间的关联关系。终端设备可以在不同的实现场景中使用对应的实现方式，根据该第二指示信息确定出至少两个候选SSB组位置所具有的关联关系。Specifically, the second indication information used to determine the association relationship between at least two candidate SSB group positions among the multiple candidate SSB group positions may be implemented in various manners. The second indication information may specifically indicate the association relationship between different SSB groups in the at least two candidate SSB group positions, and/or the second indication information may specifically indicate that the different SSB groups in the at least two candidate SSB group positions The relationship between the included at least one candidate SSB location. The terminal device may use corresponding implementation manners in different implementation scenarios, and determine the association relationship of at least two candidate SSB group positions according to the second indication information.

在一种可能的实现方式中，终端设备可以不执行步骤S103接收来自网络设备的第二指示信息，而通过其它方式获取得到第二指示信息，例如通过在预存于终端设备的存储模块中进行读取得到第二指示信息，或者是终端设备在侧行链路通信中接收其它的终端设备的信息中得到第二指示信息，还可以是其它的实现方式，此处不做限定。In a possible implementation manner, the terminal device may not perform step S103 to receive the second indication information from the network device, but obtain the second indication information in other ways, for example, by reading in a storage module pre-stored in the terminal device Obtaining the second indication information, or obtaining the second indication information by the terminal device receiving information of other terminal devices in the sidelink communication, may also be other implementation manners, which are not limited here.

在一种可能的实现方式中，在步骤S103中，终端设备接收来自该网络设备的第二指示信息之后，终端设备可以根据该第二指示信息确定该关联关系。具体地，终端设备可以根据来自网络设备的第二指示信息确定多个候选SSB组位置中，至少两个候选SSB组位置所具有的关联关系，即终端设备可以依据网络设备的指示确定该关联关系，使得终端设备可以与网络设备对齐该关联关系的配置。In a possible implementation manner, in step S103, after the terminal device receives the second indication information from the network device, the terminal device may determine the association relationship according to the second indication information. Specifically, the terminal device can determine, according to the second indication information from the network device, the association relationship between at least two candidate SSB group positions among the multiple candidate SSB group positions, that is, the terminal device can determine the association relationship according to the indication of the network device. , so that the terminal device can align the configuration of the association relationship with the network device.

进一步地，该终端设备还可以根据该第二指示信息和第三指示信息确定该关联关系，其中，该第三指示信息包括该多个候选同步信号块SSB组位置(即第一指示信息)、多个候选SSB位置、多个SSB组位置和/或SSB数量。具体地，终端设备可以进一步根据第二指示信息和第三指示信息，确定多个候选SSB组位置中，至少两个候选SSB组位置所具有的关联关系，其中，第三指示信息具体可以包括在一个或多个监听窗口中多个候选同步信号块SSB组位置(即第一指示信息)、多个候选SSB位置、多个SSB组位置和/或SSB数量。由于该第三指示信息指示在一个或多个监听窗口中SSB或SSB组的信息，即终端设备在该关联关系的确定过程中，使用第三指示信息和第二指示信息联合确定，可以优化该关联关系的确定过程。Further, the terminal device may also determine the association relationship according to the second indication information and the third indication information, wherein the third indication information includes the positions of the multiple candidate synchronization signal blocks SSB group (ie the first indication information), Multiple candidate SSB locations, multiple SSB group locations, and/or number of SSBs. Specifically, the terminal device may further determine the association relationship between at least two candidate SSB group positions among the multiple candidate SSB group positions according to the second indication information and the third indication information, wherein the third indication information may be specifically included in the Multiple candidate synchronization signal block SSB group positions (ie, first indication information), multiple candidate SSB positions, multiple SSB group positions and/or SSB numbers in one or more listening windows. Since the third indication information indicates the information of the SSB or SSB group in one or more listening windows, that is, the terminal device uses the third indication information and the second indication information to jointly determine in the process of determining the association relationship, it is possible to optimize the The process of determining the relationship.

此外，该第二指示信息对应的比特数可以为m个，其中，该m为2或3，或者是其它的取值，例如1、4、5等，且m的不同的取值可以对应于第二指示信息所指示关联关系的不同实现方式。In addition, the number of bits corresponding to the second indication information may be m, where m is 2 or 3, or other values, such as 1, 4, 5, etc., and different values of m may correspond to Different implementations of the association relationship indicated by the second indication information.

下面将通过具体的示例对第二指示信息的不同实现过程进行描述，对于第二指示信息的实现方式，可通过如下几种方式中的至少一种进行表示：The following will describe different implementation processes of the second indication information through specific examples. The implementation manner of the second indication information can be represented by at least one of the following manners:

一、定义Q ₁值为第二指示信息，其取值{1，2，4，8}。 1. Define the value of Q ₁ as the second indication information, which takes values {1, 2, 4, 8}.

本实施例中，用于表示循环移位(cyclically shift)的组，不同SSB位置所在的候选组位置或者候选SSB位置具有QCL关系，对应参数“groupPresence”，即第二指示信息可以通过无线资源管理(radio resource control，RRC)信令配置，通过MIB参数中的2-bits表示，其表示方法如下之一：In this embodiment, it is used to indicate a cyclically shifted group, and the candidate group positions or candidate SSB positions where different SSB positions are located have a QCL relationship, and the corresponding parameter "groupPresence", that is, the second indication information can be managed by the radio resource (radio resource control, RRC) signaling configuration, which is represented by 2-bits in MIB parameters, and its representation method is one of the following:

表示、第三指示信息中的多个SSB组位置(或多个组位置)通过X表示。其中，X可以通过如下两种之一或者联合表示： For the concept of QCL-based SSB groups, at candidate group positions or candidate SSB positions within one or across (multiple) DRS windows, groups with QCL relationships satisfy the formula

or (X mod Q ₁ ) or (Z mod Q ₁ ). Wherein, the positions of multiple candidate synchronization signal blocks SSB groups in the third indication information (that is, the first indication information) are represented by Z, and the number of SSBs in the third indication information is represented by

Indicates that multiple SSB group positions (or multiple group positions) in the third indication information are represented by X. Among them, X can be represented by one or a combination of the following two:

i)PBCH负载中的3个比特

表示， i) 3 bits in PBCH payload

express,

ii)PBCH DMRS序列的3-bits表示。ii) 3-bit representation of the PBCH DMRS sequence.

二、新增定义Q ₁值，其取值{8，16，24，64}。 _2. Newly define the value of Q1, which takes the value {8, 16, 24, 64}.

本实施例中，用于表示循环移位(cyclically shift)的SSB位置(l)，由参数“groupPresence”和参数“inOneGroup”联合指示，即第二指示信息通过RRC信令配置，通过MIB参数中的2-bits表示，其表示方法如下之一：In this embodiment, the SSB position (1) used to indicate the cyclic shift (cyclically shift) is jointly indicated by the parameter "groupPresence" and the parameter "inOneGroup", that is, the second indication information is configured through RRC signaling, and is passed through the MIB parameter. The 2-bits representation of , which is represented by one of the following methods:

此时，对于Q1值，分别表示两种集合：{1，2，4，8}和{8，16，24，64}。对于终端设备来说，通过在位于不同频点上的同步栅栏(sync raster)搜索SSB位置时隐含获取Q1的集合。比如，当终端设备在频点5.020GHz左右搜索到合适SSB位置时，Q1的值为{1，2，4，8}；当终端设备在频点60GHz左右搜索到合适SSB时，Q1的值为{8，16，24，64}，如下表1(指示Q1值与频点关系)所示。At this time, for the Q1 value, two sets are respectively represented: {1, 2, 4, 8} and {8, 16, 24, 64}. For the terminal equipment, the set of Q1 is implicitly obtained when searching for the SSB position through the synchronization fence (sync raster) located on different frequency points. For example, when the terminal device searches for a suitable SSB position around 5.020GHz, the value of Q1 is {1, 2, 4, 8}; when the terminal device searches for a suitable SSB at around 60GHz, the value of Q1 is {8, 16, 24, 64}, as shown in Table 1 below (indicating the relationship between Q1 values and frequency points).

表1Table 1

频点Frequency	Q ₁值 _Q1 value

大于7GHz(或大于6GHz)Greater than 7GHz (or greater than 6GHz)	{8，16，24，64}{8, 16, 24, 64}

三、定义Q ₁取值为{1，2，4，8，16，32，64}。 3. Define Q ₁ as {1, 2, 4, 8, 16, 32, 64}.

本实施例中，用于表示循环移位的SSB位置，即不同SSB及其所在的组位置，在满足公式的候选SSB位置上或者候选组位置上具有QCL关系，即第二指示信息通过RRC信令配置，通过MIB参数中的3-bits表示，其表示方法如下之一：In this embodiment, the SSB positions used to indicate the cyclic shift, that is, different SSBs and their group positions, have a QCL relationship at the candidate SSB positions or the candidate group positions that satisfy the formula, that is, the second indication information is transmitted through the RRC signal. The command configuration is represented by 3-bits in the MIB parameter, and its representation method is one of the following:

a)“公共子载波间隔subCarrierSpacingCommon”(1-bit)+“同步信号块子载波偏移ssb-SubcarrierOffset”(任意1-bit)+“控制资源集零controlResourceSetZero”(任意1-bit)；a) "common subcarrier spacing subCarrierSpacingCommon" (1-bit) + "synchronization signal block subcarrier offset ssb-SubcarrierOffset" (any 1-bit) + "control resource set zero controlResourceSetZero" (any 1-bit);

b)“公共子载波间隔subCarrierSpacingCommon”(1-bit)+“同步信号块子载波偏移ssb-SubcarrierOffset”(任意1-bit)+“搜索空间零searchSpaceZero”(任意1-bit)；b) "common subcarrier spacing subCarrierSpacingCommon" (1-bit) + "synchronization signal block subcarrier offset ssb-SubcarrierOffset" (any 1-bit) + "search space zero searchSpaceZero" (any 1-bit);

c)“公共子载波间隔subCarrierSpacingCommon”(1-bit)+“控制资源集零controlResourceSetZero”(任意2-bit)；c) "common subcarrier spacing subCarrierSpacingCommon" (1-bit) + "control resource set zero controlResourceSetZero" (any 2-bit);

d)“公共子载波间隔subCarrierSpacingCommon”(1-bit)+“搜索空间零searchSpaceZero”(任意2-bit)；d) "common subcarrier spacing subCarrierSpacingCommon" (1-bit) + "search space zero searchSpaceZero" (any 2-bit);

e)“同步信号块子载波偏移ssb-SubcarrierOffset”(任意1-bit)+“控制资源集零controlResourceSetZero”(任意2-bit)；e) "synchronization signal block subcarrier offset ssb-SubcarrierOffset" (any 1-bit) + "control resource set zero controlResourceSetZero" (any 2-bit);

f)“同步信号块子载波偏移ssb-SubcarrierOffset”(任意1-bit)+“搜索空间零searchSpaceZero”(任意2-bit)；f) "synchronization signal block subcarrier offset ssb-SubcarrierOffset" (any 1-bit) + "search space zero searchSpaceZero" (any 2-bit);

g)“控制资源集零controlResourceSetZero”(任意2-bits)+“搜索空间零searchSpaceZero”(任意1-bit)；g) "control resource set zero controlResourceSetZero" (any 2-bits) + "search space zero searchSpaceZero" (any 1-bit);

h)“控制资源集零controlResourceSetZero”中的任意3-bits；h) Any 3-bits in "controlResourceSetZero";

i)“搜索空间零searchSpaceZero”(任意2-bits)+“控制资源集零controlResourceSetZero”(任意1-bit)；i) "search space zero searchSpaceZero" (any 2-bits) + "control resource set zero controlResourceSetZero" (any 1-bit);

j)“搜索空间零searchSpaceZero”中的任意3-bits。j) Any 3-bits in "searchSpaceZero".

其中，参数“controlResourceSetZero”和“searchSpaceZero”皆位于“pdcch-ConfigSIB1”中。“任意1-bit”还包括参数“ssb-SubcarrierOffset”、“controlResourceSetZero”或“searchSpaceZero”中的高阶位1-bit或者低阶位1-bit；“任意2-bits”还包括参数“controlResourceSetZero”或“searchSpaceZero”中的高阶位2-bits或者低阶位2-bits；“任意3-bits”还包括参数“controlResourceSetZero”或“searchSpaceZero”中的高阶位3-bits或者低阶位3-bits。The parameters "controlResourceSetZero" and "searchSpaceZero" are both located in "pdcch-ConfigSIB1". "Any 1-bit" also includes the high-order 1-bit or low-order 1-bit in the parameters "ssb-SubcarrierOffset", "controlResourceSetZero" or "searchSpaceZero"; "Any 2-bits" also includes the parameter "controlResourceSetZero" Or high-order 2-bits or low-order 2-bits in "searchSpaceZero"; "any 3-bits" also includes high-order 3-bits or low-order 3-bits in parameter "controlResourceSetZero" or "searchSpaceZero" bits.

具体地，上述第二指示信息的不同取值可以对应得到不同的Q ₁的值，比如，“000”表示的Q ₁的值为“1”，“001”表示的Q ₁的值为“2”，依次类推。该取值和网络设备发送的SSB位置个数有关，比如参数“ServingCellConfigCommon”中的“ssb-PositionsInBurst”，当在“ssb-PositionsInBurst”中配置的参数为“shortBitmap”时，表示网络设备在一个时间段内(比如5ms的半帧或一个SS burst set)，最多只能发送4个SSBs，当在“ssb-PositionsInBurst”中配置的参数为“mediumBitmap”时，表示网络设备在一个时间段内(比如5ms的半帧或一个SS burst set)，最多只能发送8个SSBs。针对以上两种情况，一种实现方式是，参数“ServingCellConfigCommonSIB”中的“ssb-PositionsInBurst”的参数“groupPresence”可配置成“10000000”，即只有一个组内的SSB能够发送出来，此时Q ₁表示用于计算具有QCL关系的SSB位置，且SSB位置的个数不大于8。 Specifically, different values of the above-mentioned second indication information can correspond to different values of Q ₁ , for example, the value of Q ₁ represented by "000" is "1", and the value of Q ₁ represented by "001" is "2"",And so on. The value is related to the number of SSB positions sent by the network device, such as "ssb-PositionsInBurst" in the parameter "ServingCellConfigCommon". Within a segment (such as a 5ms half-frame or an SS burst set), only 4 SSBs can be sent at most. When the parameter configured in "ssb-PositionsInBurst" is "mediumBitmap", it means that the network device is in a period of time (such as 5ms half frame or an SS burst set), only a maximum of 8 SSBs can be sent. For the above two situations, an implementation method is that the parameter "groupPresence" of "ssb-PositionsInBurst" in the parameter "ServingCellConfigCommonSIB" can be configured to "10000000", that is, only one SSB in a group can be sent out. At this time, Q ₁ Indicates that it is used to calculate the SSB positions with QCL relationship, and the number of SSB positions is not more than 8.

当在“ssb-PositionsInBurst”中配置的参数为“longBitmap”时，表示网络设备在一个时间段内(比如5ms的半帧或一个SS burst set)，最多只能发送64个SSBs。此时，参数“ServingCellConfigCommonSIB”中“ssb-PositionsInBurst”中参数“groupPresence”值为“1”的数量大于1。其中，参数Q ₁的表示方式有如下三种含义： When the parameter configured in "ssb-PositionsInBurst" is "longBitmap", it means that the network device can only send a maximum of 64 SSBs within a time period (such as a 5ms half frame or an SS burst set). At this time, the number of the parameter "groupPresence" value "1" in "ssb-PositionsInBurst" in the parameter "ServingCellConfigCommonSIB" is greater than 1. Among them, the representation of parameter Q ₁ has the following three meanings:

i){1，2，4，8}表示用于计算获取不同候选组位置上具有QCL关系的组位置；i) {1, 2, 4, 8} indicates that the group positions with QCL relationship on different candidate group positions are obtained by calculation;

ii){16，32，64}表示用于计算获取不同候选组位置或者候选SSB位置上具有QCL关系的SSB位置；ii) {16, 32, 64} indicates that it is used to calculate and obtain SSB positions with QCL relationship on different candidate group positions or candidate SSB positions;

iii){1，2，4，8，16，32，64}表示用于计算获取不同候选组位置或者候选SSB位置上具有QCL关系的SSB位置。iii) {1, 2, 4, 8, 16, 32, 64} represents the SSB positions used to calculate and obtain different candidate group positions or candidate SSB positions with a QCL relationship.

具体地，可以通过公式

或(X mod Q ₃)或(Z mod Q ₃)确定具有QCL关系的SSB组位置，Q ₃为Q ₁中的低阶位3-bits或者高阶位3-bits，Y为通过PBCH payload中的

和3-bits的DMRS序列，共计6-bits表示的数值。其中，第三指示信息中的多个候选同步信号块SSB组位置(即第一指示信息)通过Z表示、第三指示信息中的SSB数量通过

表示、第三指示信息中的多个SSB组位置(或多个SSB组位置)通过X表示。 Specifically, through the formula

Or (X mod Q ₃ ) or (Z mod Q ₃ ) to determine the position of the SSB group with the QCL relationship, Q ₃ is the low-order 3-bits or high-order 3-bits in Q ₁ , and Y is the PBCH payload. of

And the DMRS sequence of 3-bits, a total of 6-bits represents the value. Wherein, the positions of multiple candidate synchronization signal blocks SSB groups in the third indication information (that is, the first indication information) are represented by Z, and the number of SSBs in the third indication information is represented by

Indicates that multiple SSB group positions (or multiple SSB group positions) in the third indication information are represented by X.

此外，可以通过公式

或(Y mod Q ₄)获取满足具有QCL关系的SSB位置，Y为通过PBCH payload中的

和3-bits的DMRS序列，共计6-bits表示的数值，Q ₄为Q ₁中表示{16，32，64}的三位比特，取值为{16，32，64}，比如低阶位3-bits或者高阶位3-bits；或者Q ₄即为Q ₁。 In addition, the formula can be

Or (Y mod Q ₄ ) to obtain the SSB position that satisfies the QCL relationship, and Y is passed through the PBCH payload

And the DMRS sequence of 3-bits, a total of 6-bits represents the value, Q ₄ is the three bits of Q ₁ representing {16, 32, 64}, the value is {16, 32, 64}, such as low-order bits 3-bits or high-order 3-bits; or Q ₄ is Q ₁ .

S104、网络设备根据关联关系在多个候选SSB组位置中的至少一个候选SSB组位置发送SSB。S104: The network device sends the SSB at at least one candidate SSB group position among the multiple candidate SSB group positions according to the association relationship.

S105、终端设备根据所述第一指示信息和所述关联关系在监听窗口内检测SSB。S105. The terminal device detects the SSB within the listening window according to the first indication information and the association relationship.

本实施例中，网络设备在步骤S104中根据关联关系在多个候选SSB组位置中的至少一个候选SSB组位置发送SSB。相应的，终端设备在步骤S105中可以根据步骤S102接收得到的第一指示信息和至少两个候选SSB组位置所具有的关联关系，在监听窗口内检测SSB。In this embodiment, in step S104, the network device sends the SSB at at least one candidate SSB group position among the multiple candidate SSB group positions according to the association relationship. Correspondingly, in step S105, the terminal device may detect the SSB within the listening window according to the first indication information received in step S102 and the association relationship between the positions of the at least two candidate SSB groups.

需要说明的是，对于终端设备在步骤S105中所使用的的关联关系，由步骤S103的描述可知，终端设备可以通过多种方式获取得到第二指示信息，并通过该第二指示信息确定至少两个候选SSB组位置所具有的关联关系，而不仅仅局限于步骤S103中的获取方式。本实施例中以终端设备通过步骤S103获取得到第二指示信息的实现方式为例进行说明。It should be noted that, for the association relationship used by the terminal device in step S105, it can be seen from the description of step S103 that the terminal device can obtain the second indication information in various ways, and determine at least two indications through the second indication information. The association relationship of each candidate SSB group position is not limited to the acquisition method in step S103 . In this embodiment, an implementation manner in which the terminal device obtains the second indication information through step S103 is used as an example for description.

在一种可能的实现方式中，在步骤S104中，多个候选SSB组位置中至少两个候选SSB组位置所具有的关联关系可以存在多种实现方式，此时，网络设备也可以通过多种实现方式发送SSB。In a possible implementation manner, in step S104, there may be multiple implementation manners for the association relationship of at least two candidate SSB group positions in the multiple candidate SSB group positions. The implementation sends the SSB.

例如，当多个候选SSB组位置包括第一候选SSB组位置和第二候选SSB组位置，且该第一候选SSB组位置和该第二候选SSB组位置具有该关联关系时，在步骤S104中，网络设备根据该关联关系在该多个候选SSB组位置中的至少一个候选SSB组位置发送SSB的过程可以包括：该网络设备在该第一候选SSB组位置前进行LBT；如果LBT失败，则该网络设备在该第二候选组SSB位置发送该SSB。其中，网络设备在发送SSB之前需要进行LBT，如果网络设备在第一候选SSB组位置进行LBT失败，则该网络设备在与该第一候选SSB组位置具有该关联关系的第二候选SSB组位置发送SSB，使得由于LBT失败在第一候选SSB组位置未发送的SSB在第二候选SSB组位置发送。For example, when the multiple candidate SSB group positions include a first candidate SSB group position and a second candidate SSB group position, and the first candidate SSB group position and the second candidate SSB group position have the association, in step S104 , the process that the network device sends the SSB at at least one candidate SSB group position among the multiple candidate SSB group positions according to the association relationship may include: the network device performs LBT before the first candidate SSB group position; if the LBT fails, then The network device sends the SSB at the second candidate group SSB location. The network device needs to perform LBT before sending the SSB. If the network device fails to perform LBT at the first candidate SSB group position, the network device is at the second candidate SSB group position that has the association relationship with the first candidate SSB group position. SSBs are sent so that SSBs not sent at the first candidate SSB group position due to LBT failure are sent at the second candidate SSB group position.

又如，当多个候选SSB组位置包括第三候选SSB组位置和第四候选SSB组位置，其中，该第三候选SSB组位置包括第一候选SSB位置，该第四候选SSB位置包括第二候选SSB位置，且该第三候选SSB组位置和该第四候选SSB组位置具有该关联关系，该第一SSB位置和该第二SSB位置具有该关联关系时，在步骤S104中，网络设备根据该关联关系在该多个候选SSB组位置中的至少一个候选SSB组位置发送SSB的过程可以包括：该网络设备在该第一候选SSB位置进行LBT；如果LBT失败，则该网络设备在该第二候选SSB位置发送该SSB。其中，网络设备在发送SSB之前需要进行LBT，如果网络设备在第三候选SSB组位置中的第一候选SSB位置进行LBT失败，则该网络设备在与该第三候选SSB组位置具有该关联关系的第四候选SSB组位置中，与该第一候选SSB位置具有该关联关系的第二候选SSB位置发送SSB，使得由于LBT失败在第一候选SSB位置未发送的SSB在第二候选SSB位置发送。For another example, when the multiple candidate SSB group positions include a third candidate SSB group position and a fourth candidate SSB group position, wherein the third candidate SSB group position includes the first candidate SSB position, and the fourth candidate SSB group position includes the second candidate SSB group position The candidate SSB position, and the third candidate SSB group position and the fourth candidate SSB group position have the association relationship, and the first SSB position and the second SSB position have the association relationship, in step S104, the network device according to The process of sending the SSB in at least one candidate SSB group position of the plurality of candidate SSB group positions in the association relationship may include: the network device performs LBT at the first candidate SSB position; if the LBT fails, the network device performs LBT at the first candidate SSB group position; Two candidate SSB locations send the SSB. The network device needs to perform LBT before sending the SSB. If the network device fails to perform LBT at the first candidate SSB position in the third candidate SSB group position, the network device has the association relationship with the third candidate SSB group position. In the fourth candidate SSB group position, the second candidate SSB position that has the association relationship with the first candidate SSB position sends the SSB, so that the SSB that is not sent at the first candidate SSB position due to the LBT failure is sent at the second candidate SSB position. .

下面将通过具体的示例对网络设备在步骤S104中的发送方式进行描述。The sending manner of the network device in step S104 will be described below by using a specific example.

方式一、LBT成功所在SSB组内实际发送的SSB图样不发生改变。Mode 1: The SSB pattern actually sent in the SSB group where the LBT succeeds does not change.

在该实现方式中，候选SSB组将以循环移位的方式出现在一个或者跨(多个)DRS窗口内的候选组位置或者候选SSB位置上，每个组位置内实际发送的SSB位置(即参数“inOneGroup”)虽也会跟随所在组的循环移位出现循环移位，也具有QCL关系，但每个组位置内的SSB图样、网络设备发送的方式、顺序等依旧不变，即参数“inOneGroup”内的SSB图样不变。In this implementation, candidate SSB groups will appear in a cyclic shift at candidate group positions or candidate SSB positions within one or across (multiple) DRS windows, and the actually transmitted SSB positions within each group position (ie, Although the parameter "inOneGroup") will also follow the cyclic shift of the group in which it belongs, it also has a QCL relationship, but the SSB pattern in each group position, the method and order of network device transmission, etc. remain unchanged, that is, the parameter " The SSB pattern in inOneGroup" remains unchanged.

当LBT发生在某个候选组位置(候选组位置Z)内，且gNB在该候选组位置内LBT成功占用信道。When LBT occurs in a certain candidate group position (candidate group position Z), and the gNB successfully occupies the channel by LBT in the candidate group position.

对于LBT成功所在组之前的SSB--从gNB角度来说，该候选组位置之前如果存在需要在其它候选组位置上发送的SSB位置(比如参数“GroupPresence”置为“1”)，则之前的这些候选组位置在满足QCL关系的候选组位置或者候选SSB位置上将组内的SSB位置全部发送出来，即所发送的组位置(X)在候选组位置(Z)上以循环移位的方式出现。从UE的角度来说，它在满足QCL关系的候选组位置监听组内的SSB位置，或者在满足QCL关系的候选SSB位置上检测SSB位置。For the SSB before the group where the LBT succeeds - from the gNB point of view, if there is an SSB position that needs to be sent on other candidate group positions before the candidate group position (for example, the parameter "GroupPresence" is set to "1"), then the previous These candidate group positions send all the SSB positions in the group at the candidate group positions or candidate SSB positions that satisfy the QCL relationship, that is, the sent group position (X) is cyclically shifted on the candidate group position (Z). Appear. From the UE's point of view, it monitors the SSB positions within the group at the candidate group positions satisfying the QCL relationship, or detects the SSB positions at the candidate SSB positions satisfying the QCL relationship.

对于LBT成功所在组的SSB--LBT成功发生在的某个候选组位置(Z)，对于gNB来说，它所发送的组位置(X)将以循环移位的方式出现，当gNB在某个候选组位置内LBT成功占用信道之后，该候选组位置内的SSB位置不会发送，而是在满足QCL关系的候选组位置或者候选SSB位置上发送SSB位置。从UE的角度来说，它在满足QCL关系的候选组位置监听组内的SSB位置，或者在满足QCL关系的候选SSB位置上检测SSB位置。For the SSB of the group where the LBT succeeds—a candidate group position (Z) where the LBT successfully occurs, for the gNB, the group position (X) it sends will appear in a cyclic shift. When the gNB is in a certain group position (Z) After the LBT in each candidate group position successfully occupies the channel, the SSB position in the candidate group position will not be sent, but the SSB position will be sent at the candidate group position or the candidate SSB position that satisfies the QCL relationship. From the UE's point of view, it monitors the SSB positions within the group at the candidate group positions satisfying the QCL relationship, or detects the SSB positions at the candidate SSB positions satisfying the QCL relationship.

在该实现方式中，每个组位置内实际发送的SSB位置图样、个数和SSB位置的相对位置保持不变。In this implementation manner, the actually sent SSB position pattern, number and relative position of the SSB positions in each group position remain unchanged.

以图6为例，首先对图6所示各类方框所示内容进行说明。假设一个DRS窗口(或者一个半帧或者一个SS burst set周期)为5ms，在5ms的监听窗口内网络设备以图2所示方式(“groupPresence＝10101011,inOneGroup＝10101011”)在阴影块#0～#19上发送SSB。在阴影块#0～#19上，参数groupPresence＝10101011指示在#0～#19上的#0、#2、#4、#6、#7、#8、#10、#12、#14、#15、#16、#18等多个位置为网络设备可能发送的SSB组位置；在每一个阴影块#0～#19内部，参数inOneGroup＝10101011指示在任意一个阴影块的多个SSB组位置内网络设备可能发送的SSB位置。以#0为例，其包括虚线框#0-7对应的SSB位置，参数inOneGroup＝10101011指示在#0所示虚线框#0-7位置上网络设备可能发送的SSB位置，其中，虚线框#0-7的SSB位置可以如图6中加粗虚线框所示。Taking FIG. 6 as an example, the contents of the various blocks shown in FIG. 6 will be described first. Assuming that a DRS window (or a half-frame or a SS burst set period) is 5ms, within the 5ms listening window, the network device is in the shaded block #0~ Send SSB on #19. On the shaded blocks #0 to #19, the parameter groupPresence=10101011 indicates #0, #2, #4, #6, #7, #8, #10, #12, #14, #15, #16, #18 and other locations are the SSB group locations that may be sent by network devices; within each shaded block #0 to #19, the parameter inOneGroup=10101011 indicates multiple SSB group locations in any shaded block The location of the SSB that the internal network device may send. Taking #0 as an example, it includes the SSB position corresponding to the dotted frame #0-7, and the parameter inOneGroup=10101011 indicates the SSB position that the network device may send at the position of the dotted frame #0-7 shown in #0, wherein the dotted frame# The SSB positions of 0-7 can be shown as bold dashed boxes in FIG. 6 .

此外，由此前图2所示描述可知，此处以网络设备在5ms窗口内发送的SSB数量最大为64为例，即可能存在两个或三个相同的空白框#0～#7，例如在图示中存在三个相同的空白框#0、#1、#2、#3，存在两个相同的空白框#4、#5、#6、#7。其中，相同的空白框表示所发送的SSB位置相同，比如，空白框#0对应的虚线框#0-7、#64-71、#128-135对应的SSB位置所承载的SSB相同；又如，空白框#5对应的虚线框#40-47、#104-111对应的SSB位置所承载的SSB相同。In addition, from the previous description shown in Figure 2, it can be seen that the maximum number of SSBs sent by the network device in the 5ms window is 64 as an example, that is, there may be two or three identical blank boxes #0~#7, for example, in Figure There are three identical blank boxes #0, #1, #2, #3 in the display, and two identical blank boxes #4, #5, #6, #7. Among them, the same blank box indicates that the transmitted SSB positions are the same, for example, the SSB positions carried by the SSB positions corresponding to the dotted boxes #0-7, #64-71, and #128-135 corresponding to the blank box #0 are the same; , the SSBs carried by the SSB positions corresponding to the dotted boxes #40-47 and #104-111 corresponding to the blank box #5 are the same.

当网络设备通过图6的方式执行步骤S104时，假设候选组位置#0和候选组位置#8，以及候选组位置#2和候选组位置#10满足某种QCL关系。LBT发生在候选组位置#2内，该候选组位置内的{候选SSB位置#16～候选SSB位置#23}上的SSB都将不会发送出来，而在满足QCL关系的候选组位置上(如候选组位置#10)上发送候选组位置#2上组位置#2内的所有SSB位置。即在候选SSB位置{候选SSB位置#80～候选SSB位置#87}上发送参数“inOneGroup”中配置为“1”的SSB位置。对于候选组位置#0上组位置#0内的SSB位置，它将在满足QCL关系的候选SSB位置#8上的候选SSB位置上发送SSB，或者在满足QCL关系的候选SSB位置上发送SSB位置。对于其它组位置内需要发送的SSB位置，根据LBT类型以及剩余占用的信道占用时间(channel occupancy time，COT)长度在候选组位置或者候选SSB位置上发送其它组位置内的SSB位置。When the network device performs step S104 in the manner of FIG. 6 , it is assumed that the candidate group position #0 and the candidate group position #8, and the candidate group position #2 and the candidate group position #10 satisfy a certain QCL relationship. LBT occurs in candidate group position #2, SSBs in {candidate SSB position #16 ~ candidate SSB position #23} in this candidate group position will not be sent, but in the candidate group position that satisfies the QCL relationship ( For example, on candidate group position #10), all SSB positions within group position #2 on candidate group position #2 are sent. That is, the SSB positions configured as "1" in the parameter "inOneGroup" are sent in the candidate SSB positions {candidate SSB position #80 to candidate SSB position #87}. For SSB positions within group position #0 on candidate group position #0, it will send the SSB on the candidate SSB position on candidate SSB position #8 that satisfies the QCL relationship, or the SSB position on the candidate SSB position that satisfies the QCL relationship . For the SSB positions that need to be sent in other group positions, according to the LBT type and the remaining occupied channel occupancy time (channel occupancy time, COT) length, the SSB positions in the other group positions are sent at the candidate group position or the candidate SSB position.

相应地，当网络设备通过图6所示方式执行步骤S104时，终端设备在步骤S105中可以根据步骤S102接收得到的第一指示信息以及步骤S103接收得到的第二指示信息检测网络设备所发送的SSB。对于UE来说，在一个或者跨(多个)DRS窗口内，具有QCL关系的组位置内的SSB位置具有QCL关系。同时，在一个DRS窗口内，在一个服务小区内实际发送的组的数量将不大于Q ₁，实际发送的SSB(l)的数量将不大于Q ₂，且包含相同SSB位置(l)的组的数量以及具有相同SSB位置(l)的数量都不大于1。(The UE assumes that within a discovery burst transmission window，a number of transmitted group index on a serving cell is not larger than Q ₁and a number of transmitted group index contains the same SS/PBCH block index is not larger than one，a number of transmitted SS/PBCH block index on a serving cell is not larger than Q ₂and a number of transmitted SS/PBCH blocks with a same SS/PBCH block index is not larger than one.) Correspondingly, when the network device executes step S104 in the manner shown in FIG. 6 , the terminal device can detect, in step S105, the first indication information received by the network device and the second indication information received by the step S103. SSB. For the UE, within one or across DRS window(s), SSB locations within a group location with a QCL relationship have a QCL relationship. At the same time, within a DRS window, the number of groups actually sent in a serving cell will not be greater than Q ₁ , and the number of SSBs (l) actually sent will be no greater than Q ₂ , and include groups with the same SSB position (l). The number of and the number with the same SSB position (l) is neither greater than 1. (The UE assumes that within a discovery burst transmission window, a number of transmitted group index on a serving cell is not larger than Q ₁ and a number of transmitted group index contains the same SS/PBCH block index is not larger than one, a number of transmitted SS/PBCH block index on a serving cell is not larger than Q ₂ and a number of transmitted SS/PBCH blocks with a same SS/PBCH block index is not larger than one.)

此外，终端设备在步骤S105中可以根据第二指示信息所确定的不同的关联关系，对应检测SSB，下面将详细描述。In addition, the terminal device may detect the SSB correspondingly according to the different association relationships determined by the second indication information in step S105, which will be described in detail below.

对应于方式一所示实施例，引入了具有QCL关系的组的概念，UE根据基于组的QCL关系，可以准确的获取实际SSB的发送位置，以方便做好速率匹配。Corresponding to the embodiment shown in the first mode, the concept of a group with a QCL relationship is introduced, and the UE can accurately obtain the actual SSB sending position according to the group-based QCL relationship, so as to facilitate rate matching.

方式二、LBT成功所在SSB组内，以及其它SSB组内实际发送的SSB图样发生改变。Mode 2: The SSB group in which the LBT succeeds is located, and the SSB pattern actually sent in other SSB groups changes.

在该实施例中，候选SSB组位置将以循环移位的方式出现在一个或者跨(多个)DRS窗口内的候选组位置或者候选SSB位置上，每个组位置内实际发送的SSB位置(即参数“inOneGroup”)也会跟随组位置的循环移位出现循环移位，也具有QCL关系，每个组位置内的SSB图样或网络设备发送的方式也会随之改变。即同时对组位置(参数“GroupPresence”)和组位置内实际发送的SSB位置(参数“InOneGroup”)进行循环移位。In this embodiment, candidate SSB group positions will appear in a cyclic shift at candidate group positions or candidate SSB positions within one or across (multiple) DRS windows, and the actually transmitted SSB positions in each group position ( That is, the parameter "inOneGroup") will also follow the cyclic shift of the group position, and it also has a QCL relationship. The SSB pattern in each group position or the transmission method of the network device will also change accordingly. That is, the group position (parameter "GroupPresence") and the actually sent SSB position (parameter "InOneGroup") in the group position are cyclically shifted at the same time.

对于LBT成功所在组之前的SSB--从gNB角度来说，该候选组位置之前如果存在需要在其它候选组位置上发送的SSB位置(比如参数“GroupPresence”置为“1”)，则之前的这些候选组位置在满足QCL关系的选组位置或者候选SSB位置

上将组内的SSB位置全部发送出来，即所发送的组位置(X)在候选组位置(Z)上以循环移位的方式出现。 For the SSB before the group where the LBT succeeds - from the gNB point of view, if there is an SSB position that needs to be sent on other candidate group positions before the candidate group position (for example, the parameter "GroupPresence" is set to "1"), then the previous These candidate group positions are in the selected group positions or candidate SSB positions that satisfy the QCL relationship

All the SSB positions in the group are sent out, that is, the sent group position (X) appears in the form of cyclic shift on the candidate group position (Z).

对于LBT成功所在组的SSB--LBT成功发生在的某个候选组位置(Z)，对于gNB来说，它所发送的组位置将以循环移位的方式在多个候选组位置或者候选SSB位置上出现，这些候选组位置或者候选SSB位置上发送的组位置相同，即满足QCL关系。同时，每个组位置内实际发送的SSB位置，都会基于LBT所在候选组位置上的SSB实际发送情况以及改变。此时，gNB发送组位置的个数大于参数“GroupPresence”中比特置为“1”的个数。For the SSB of the group where the LBT is successful--a candidate group position (Z) where the LBT successfully occurs, for the gNB, the group position sent by it will be in multiple candidate group positions or candidate SSBs in a cyclic shift manner appear in the position, the group positions sent at these candidate group positions or candidate SSB positions are the same, that is, the QCL relationship is satisfied. At the same time, the actually sent SSB position in each group position will be based on the actual sending situation and change of the SSB at the candidate group position where the LBT is located. At this time, the number of group positions sent by the gNB is greater than the number of bits set to "1" in the parameter "GroupPresence".

以图7为例，其中，图7中各类方框所示内容可以参考前述图6中各类方框所示内容的说明，此处不再赘述。如下图7所示，“GroupPresence＝10101011”，即有5个组位置的SSB位置将会被发送出来，此时，gNB根据QCL关系，在不同候选组位置或者候选SSB位置上发送的同一个组位置至少需要两次，即在该图7中第#2和第#10的候选组位置上，都能够发送出组位置为#2内的SSB位置。Taking FIG. 7 as an example, for the content shown in various blocks in FIG. 7 , reference may be made to the description of the content shown in the various blocks in FIG. 6 , which will not be repeated here. As shown in Figure 7 below, "GroupPresence=10101011", that is, SSB positions with 5 group positions will be sent. At this time, the gNB sends the same group at different candidate group positions or candidate SSB positions according to the QCL relationship. The position needs to be at least twice, that is, at the candidate group positions of #2 and #10 in FIG. 7 , the SSB position within the group position of #2 can be sent.

此外，每个候选组位置上的组位置内实际发送的SSB位置也将在其所在组位置位于其它多个候选组位置或者候选SSB位置上出现。当gNB在某个候选组位置内LBT成功占用信道之后，该候选组位置上LBT成功之后的SSB位置将会发送出来，但是该组位置内LBT成功所处的时间点之前的SSB位置将会在满足QCL关系的候选组位置或者候选SSB位置上发送。但是，每个组位置内实际发送的SSB位置图样、索引个数和SSB位置的相对位置保持不变。In addition, the actually transmitted SSB position in the group position on each candidate group position will also appear when the group position where the group position is located is located in other multiple candidate group positions or candidate SSB positions. When the gNB successfully occupies the channel by LBT in a candidate group position, the SSB position after the successful LBT in the candidate group position will be sent, but the SSB position in the group position before the time point when the LBT is successful will be in It is sent at the candidate group position or the candidate SSB position that satisfies the QCL relationship. However, the actually transmitted SSB position pattern, the number of indices and the relative positions of the SSB positions within each group position remain unchanged.

当网络设备通过图7的方式执行步骤S104时，LBT发生在候选组位置#2内，该组位置内的候选SSB位置#0～候选SSB位置#5上的SSB位置因LBT失败无法成功发送出来，候选SSB位置#6和候选SSB位置#7上的SSB则可以成功发送出来。此时，对于在{候选组位置#0，候选组位置#2，候选组位置#4，候选组位置#6和候选组位置#7}上的组位置，其组内的{候选SSB位置#22，候选SSB位置#23}，{候选SSB位置#38，候选SSB位置#39}，{候选SSB位置#54，候选SSB位置#55}，{候选SSB位置#62，候选SSB位置#63}等上面的SSB位置都可以发送出来。而在满足QCL关系的{候选组位置#8，候选组位置#10，候选组位置#12，候选组位置#14和候选组位置#15}，因为与{候选组位置#0，候选组位置#2，候选组位置#4，候选组位置#6和候选组位置#7}对应同一个组位置，因此，{候选组位置#8，候选组位置#10，候选组位置#12，候选组位置#14和候选组位置#15}组内发送的SSB位置分别为({候选SSB位置#64，候选SSB位置#66，候选SSB位置#68，候选SSB位置#70，候选SSB位置#71}，{候选SSB位置#80，候选SSB位置#82，候选SSB位置#84}，{候选SSB位置#96，候选SSB位置#98，候选SSB位置#100}，{候选SSB位置#112，候选SSB位置#114，候选SSB位置#116}，{候选SSB位置#120，候选SSB位置#122，候选SSB位置#124})等上面的SSB位置都可以发送出来。When the network device performs step S104 in the manner of FIG. 7 , the LBT occurs in the candidate group position #2, and the SSB positions in the candidate SSB position #0 to the candidate SSB position #5 in the group position cannot be successfully sent out due to the LBT failure. , the SSBs at candidate SSB position #6 and candidate SSB position #7 can be successfully sent. At this time, for the group positions at {candidate group position #0, candidate group position #2, candidate group position #4, candidate group position #6 and candidate group position #7}, {candidate SSB position # within the group 22, candidate SSB position #23}, {candidate SSB position #38, candidate SSB position #39}, {candidate SSB position #54, candidate SSB position #55}, {candidate SSB position #62, candidate SSB position #63} Wait until the above SSB location can be sent out. And in the {candidate group position #8, candidate group position #10, candidate group position #12, candidate group position #14 and candidate group position #15} that satisfy the QCL relationship, because the same as {candidate group position #0, candidate group position #15} #2, candidate group position #4, candidate group position #6 and candidate group position #7} correspond to the same group position, so {candidate group position #8, candidate group position #10, candidate group position #12, candidate group position #12 Position #14 and candidate group position #15} The SSB positions sent within the group are respectively ({candidate SSB position #64, candidate SSB position #66, candidate SSB position #68, candidate SSB position #70, candidate SSB position #71} , {candidate SSB location #80, candidate SSB location #82, candidate SSB location #84}, {candidate SSB location #96, candidate SSB location #98, candidate SSB location #100}, {candidate SSB location #112, candidate SSB location Position #114, candidate SSB position #116}, {candidate SSB position #120, candidate SSB position #122, candidate SSB position #124}) and other SSB positions above can be sent.

图7所示过程可以简单概括为：对于每个组位置内实际发送的SSB位置。在前8个候选组位置上，网络设备只会在候选组位置上的最后两个候选SSB位置上发送SSB位置。在后8个候选组位置上，gNB发送每个组位置中其它候选SSB位置上剩余的SSB位置。The process shown in FIG. 7 can be simply summarized as: for the actually transmitted SSB location within each group location. On the first 8 candidate group positions, the network device will only transmit the SSB positions on the last two candidate SSB positions on the candidate group positions. At the last 8 candidate group positions, the gNB transmits the remaining SSB positions over the other candidate SSB positions in each group position.

相应地，当网络设备通过图7所示方式执行步骤S104时，终端设备在步骤S105中可以根据步骤S102接收得到的第一指示信息以及步骤S103接收得到的第二指示信息检测网络设备所发送的SSB。具体地，对于UE来说，在一个或者跨(多个)DRS窗口内，具有QCL关系的组位置内的SSB位置具有QCL关系。同时，在一个DRS窗口内，在一个服务小区内实际发送的组的数量可大于Q ₁，且包含相同SSB位置(l)的组的数量可大于1，实际发送的SSB(l)的数量将不大于Q ₂，且组位置内实际发送的相同SSB位置(l)的数量不大于1。(The UE assumes that within a discovery burst transmission window,a number of transmitted group index on a serving cell can be larger than,and a number of transmitted group index provided by is“GroupPresence”can be larger than one,a number of transmitted SS/PBCH blocks on a serving cell is not larger than,and a number of transmitted SS/PBCH blocks with a same SS/PBCH block index is not larger than one.) Correspondingly, when the network device executes step S104 in the manner shown in FIG. 7 , the terminal device may detect, in step S105, the first indication information received by the network device and the second indication information received by the step S103. SSB. Specifically, for the UE, within one or across DRS window(s), SSB locations within a group location with a QCL relationship have a QCL relationship. Meanwhile, within a DRS window, the number of groups actually sent in one serving cell may be greater than Q ₁ , and the number of groups containing the same SSB position (1) may be greater than 1, and the number of actually sent SSBs (1) will be is not greater than _Q2 , and the number of identical SSB locations (1) actually transmitted within a group location is not greater than 1. (The UE assumes that within a discovery burst transmission window, a number of transmitted group index on a serving cell can be larger than, and a number of transmitted group index provided by is “GroupPresence” can be larger than one, a number of transmitted SS/PBCH blocks on a serving cell is not larger than, and a number of transmitted SS/PBCH blocks with a same SS/PBCH block index is not larger than one.)

此外，终端设备在步骤S105中可以根据第二指示信息所确定的不同的关联关系，对应检测SSB。具体来说，在终端设备在步骤S103中确定第二指示信息对应Q ₁值的取值{1,2,4,8}、或者确定第二指示信息对应Q ₁值的取值{8,16,24,64}、或者确定第二指示信息对应Q ₁值的取值{1,2,4,8,16,32,64}的实现方式可以参考前述方式一中的实现过程，此处不再赘述。 In addition, in step S105, the terminal device may detect the SSB correspondingly according to the different association relationships determined by the second indication information. Specifically, in step S103, the terminal device determines the value {1, 2, 4, 8} of the Q ₁ value corresponding to the second indication information, or determines the value {8, 16 of the Q ₁ value corresponding to the second indication information , 24, 64}, or the implementation of determining the value {1, 2, 4, 8, 16, 32, 64} of the second indication information corresponding to the Q ₁ value may refer to the implementation process in the foregoing method 1. Repeat.

对应于方式二所示实施例，引入了具有QCL关系的组位置的概念，其中，每个组位置内实际发送的SSB位置也会跟随LBT的结果在不同的候选组位置上发送。通过这种方法，可以准确的获取实际SSB位置的发送位置，以方便做好速率匹配。Corresponding to the embodiment shown in Manner 2, the concept of group positions with a QCL relationship is introduced, wherein the actually sent SSB positions in each group position are also sent in different candidate group positions following the LBT result. Through this method, the sending position of the actual SSB position can be accurately obtained, so as to facilitate rate matching.

方式三、LBT成功所在SSB组内实际发送的SSB图样发生改变。Mode 3: The SSB pattern actually sent in the SSB group where the LBT succeeds is changed.

在该实施例中，组位置将以循环移位的方式出现在一个或者跨(多个)DRS窗口内的候选组位置或者候选SSB位置上，每个组位置内实际发送的SSB位置(即参数“inOneGroup”)也会跟随组位置的循环移位出现循环移位，也具有QCL关系，LBT成功所在的候选组位置上内的SSB图样或网络设备发送的方式也会随之改变。In this embodiment, the group positions will appear in a cyclic shift at candidate group positions or candidate SSB positions within one or across (multiple) DRS windows, and the actually transmitted SSB positions (i.e. parameter "inOneGroup") also follows the cyclic shift of the group position, and also has a QCL relationship. The SSB pattern in the candidate group position where the LBT succeeds or the way the network device sends it will also change accordingly.

上将组内的SSB位置全部发送出来，即所发送的组位置(X)在候选组位置(Z)上以循环移位的方式出现。从UE的角度来说，它在满足QCL关系的候选组位置监听组内的SSB位置，或者在满足QCL关系的候选SSB位置上检测SSB位置。 For the SSB before the group where the LBT succeeds - from the gNB point of view, if there is an SSB position that needs to be sent on other candidate group positions before the candidate group position (for example, the parameter "GroupPresence" is set to "1"), then the previous These candidate group positions are in the selected group positions or candidate SSB positions that satisfy the QCL relationship

All the SSB positions in the group are sent out, that is, the sent group position (X) appears in the form of cyclic shift on the candidate group position (Z). From the UE's point of view, it monitors the SSB positions within the group at the candidate group positions satisfying the QCL relationship, or detects the SSB positions at the candidate SSB positions satisfying the QCL relationship.

对于LBT成功所在组的SSB--对于LBT成功的发生在某个候选组位置，在该候选组位置上的组位置中，LBT成功之前如果存在SSB位置需要发送(比如参数“InOneGroup”置为“1”)，gNB在满足QCL关系的候选组位置上发送SSB位置，或者在候选SSB位置上发送SSB位置；而在该候选组位置上的组位置中，LBT成功之后如果存在SSB位置需要发送(比如参数“InOneGroup”置为“1”)，gNB将在该候选组位置上的候选SSB位置发送SSB位置。从UE的角度来说，它在满足QCL关系的候选组位置监听组内的SSB位置，或者在满足 QCL关系的候选SSB位置上检测SSB位置。但是，每个组位置内实际发送的SSB位置图样、索引个数和SSB位置的相对位置保持不变。For the SSB of the group where the LBT is successful - for the LBT success that occurs in a candidate group position, in the group position on the candidate group position, if there is an SSB position before the LBT is successful, it needs to be sent (for example, the parameter "InOneGroup" is set to " 1"), the gNB sends the SSB position on the candidate group position that satisfies the QCL relationship, or sends the SSB position on the candidate SSB position; and in the group position on the candidate group position, after the LBT succeeds, if there is an SSB position, it needs to send ( For example, the parameter "InOneGroup" is set to "1"), the gNB will send the SSB position at the candidate SSB position on the candidate group position. From the UE's point of view, it monitors the SSB positions within the group at the candidate group positions satisfying the QCL relationship, or detects the SSB positions at the candidate SSB positions satisfying the QCL relationship. However, the actually transmitted SSB position pattern, the number of indices and the relative positions of the SSB positions within each group position remain unchanged.

以图8为例，其中，图8中各类方框所示内容可以参考前述图6中各类方框所示内容的说明，此处不再赘述。如下图8所示，“groupPresence＝10101011,inOneGroup＝10101011”。LBT发生在候选组位置#2上，候选组位置#0内也有SSB位置需要发送。此时，gNB在候选组位置#8上的候选SSB位置

发送具有相同组位置内的SSB位置或者相同SSB位置(l)的SSB。对于候选组位置#2内的SSB位置，网络设备在候选SSB位置#22和候选SSB位置#23上发送SSB位置。同时，在满足QCL关系的候选组位置上的候选SSB位置上发送其余因LBT失败而没有成功发送出来的SSB位置，比如在候选组#10上的{候选SSB位置#80，候选SSB位置#82，候选SSB位置#84}上发送SSB位置。其余候选组内候选SSB位置的SSB图样或发送顺序将不会发送变化。 Taking FIG. 8 as an example, for the content shown in various blocks in FIG. 8, reference may be made to the description of the content shown in the various blocks in FIG. 6, which will not be repeated here. As shown in Figure 8 below, "groupPresence=10101011, inOneGroup=10101011". LBT occurs at candidate group position #2, and there are also SSB positions within candidate group position #0 that need to be sent. At this time, the candidate SSB position of the gNB at the candidate group position #8

SSBs with either the SSB position within the same group position or the same SSB position (1) are sent. For SSB locations within candidate set location #2, the network device transmits the SSB locations on candidate SSB location #22 and candidate SSB location #23. At the same time, send the remaining SSB positions that were not successfully sent due to LBT failure at the candidate SSB positions on the candidate group positions that satisfy the QCL relationship, such as {candidate SSB position #80, candidate SSB position #82 on candidate group #10 , the SSB position is sent on the candidate SSB position #84}. The SSB pattern or transmission order of the candidate SSB positions in the remaining candidate groups will not be changed.

图8所示过程可以简单概括为：只改变LBT成功所在组内实际发送的SSB位置，其它组位置内的SSB位置的发送方式不会发生变化。The process shown in FIG. 8 can be simply summarized as: only the SSB position actually sent in the group where the LBT is successful is changed, and the sending mode of the SSB position in other group positions will not change.

相应地，当网络设备通过图8所示方式执行步骤S104时，终端设备在步骤S105中可以根据步骤S102接收得到的第一指示信息以及步骤S103接收得到的第二指示信息检测网络设备所发送的SSB。具体地，对于UE来说，在一个或者跨(多个)DRS窗口内，具有QCL关系的组位置内的SSB位置具有QCL关系。同时，在一个DRS窗口内，在一个服务小区内实际发送的组的数量可大于Q ₁，且包含相同SSB位置(l)的组的数量可大于1，实际发送的SSB(l)的数量将不大于Q ₂，且组位置内实际发送的相同SSB位置(l)的数量不大于1。(The UE assumes that within a discovery burst transmission window,a number of transmitted group on a serving cell can be larger than Q ₁,and a number of transmitted groups with a same group index provided by“GroupPresence”can be larger than one,a number of transmitted SS/PBCH blocks on a serving cell is not larger thanQ ₂,and a number of transmitted SS/PBCH blocks with a same SS/PBCH block index is not larger than one.) Correspondingly, when the network device performs step S104 in the manner shown in FIG. 8 , the terminal device can detect the data sent by the network device according to the first indication information received in step S102 and the second indication information received in step S103 in step S105 . SSB. Specifically, for the UE, within one or across DRS window(s), SSB locations within a group location with a QCL relationship have a QCL relationship. Meanwhile, within a DRS window, the number of groups actually sent in one serving cell may be greater than Q ₁ , and the number of groups containing the same SSB position (1) may be greater than 1, and the number of actually sent SSBs (1) will be is not greater than _Q2 , and the number of identical SSB locations (1) actually transmitted within a group location is not greater than 1. (The UE assumes that within a discovery burst transmission window, a number of transmitted group on a serving cell can be larger than Q ₁ , and a number of transmitted groups with a same group index provided by “GroupPresence” can be larger than one, a number of transmitted SS/PBCH blocks on a serving cell is not larger than Q ₂ ,and a number of transmitted SS/PBCH blocks with a same SS/PBCH block index is not larger than one.)
